I like it, it is much more professional looking than the previous home page. One thing I think is missing and would like to see is a comment about how wikitree is different to other trees. To me, collaboration was very important but I also love what you are trying to do with dna. It's great. Couldn't you have a dot point about bringing the two worlds together, so it appeals to both traditional genealogists and those interested in genetic genealogy? No other site facilitates comparisons of dna tests and genealogies like wikitree.
I also think the addition of profile and photo of the week is excellent too, as it changes each week it will keep the user engaged with the site.
